Ruby - 命令退出错误

Question

我对编程完全陌生，我无法弄清楚为什么在输入以下内容时出现错误：

puts "What is your favorite number?"
number = gets.chomp
number = number.to_i + 1
puts "I suggest " + number.to_s + " as a bigger and better number"

当我在终端中运行时，会出现以下错误：

What is your favorite number?

Answer 1

代码有效。你是如何运行脚本的？将它放在像number.rb这样的文件中，然后输入atexit.register(port_exit) while True: x = myPort.readline() if x == "1\r\n": scalavars.door = x scala5.ScalaPlayer.Sleep(10)

来运行它
